constant voltage required to obtain a response cur-
rent is applied across the connector 14 by a voltage
applying source 15 at timings required. A response
current of the sensor 13 Inserted Into the connector
14 is converted into a voltage by a current-to-voltage
converter 16, and the amount thereof is determined
by a microcomputer, the analysis results being dis-
played onto a display unit.
